Chemical properties of ergosta-4, 6, 8(14), 22-tetraen-3-one (1) were investigated. Though 1 is rather stable to acids or bases, it reacts easily with two moleculres of oxygen on irradiation with UV light to give 6α, 9α-epidioxy-14α-hydroperoxyergosta-4, 7, 22-trien-3-one (2), which is transformed successively to 6α, 7α;8α, 9α-diepoxy-14α-hydroperoxyergosta-4, 22-dien-3-one (3) and 14α-hydroperoxy-9α-hydroxyergosta-4, 7, 22-triene-3, 6-dione (4) under these reaction conditions.
